Need help with a C# Project

In a very simple C# Windows Form .NET Framework project in Visual Studio 2019 I have one form with the CefSharp browser.

This browser shows a fixed intranet website.

I need 2 things.

1. A whitelist, to prevent visiting other websites.

2. A custom Protocol Execution handler class. Based on the class displayed below. (I need to open an local MS Office file by clicking a href link).

public class CustomRequestHandler : [login to view URL]


protected override bool OnBeforeBrowse(IWebBrowser chromiumWebBrowser, IBrowser browser, IFrame frame, IRequest request, bool userGesture, bool isRedirect)



if ([login to view URL]("customScheme:"))


[login to view URL]([login to view URL]);

return true;


return [login to view URL](chromiumWebBrowser, browser, frame, request, userGesture, isRedirect);



[login to view URL] = new CustomRequestHandler();

Taidot: C# -ohjelmointi, .NET
